From 7330672befe6269e575f79b924a7068b26c144b4 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Fri, 25 Oct 2013 17:29:18 +0100 Subject: KVM: arm-vgic: Support KVM_CREATE_DEVICE for VGIC Support creating the ARM VGIC device through the KVM_CREATE_DEVICE ioctl, which can then later be leveraged to use the KVM_{GET/SET}_DEVICE_ATTR, which is useful both for setting addresses in a more generic API than the ARM-specific one and is useful for save/restore of VGIC state. Adds KVM_CAP_DEVICE_CTRL to ARM capabilities. Note that we change the check for creating a VGIC from bailing out if any VCPUs were created, to bailing out if any VCPUs were ever run. This is an important distinction that shouldn't break anything, but allows creating the VGIC after the VCPUs have been created.
